Inventor: VAN ROOSMALEN JOHANNES HENDRIK
IPC: H01J31/10

Abstract: A display tube comprising in an evacuated envelope (1) an electron gun system (6) for generating  . and focusing by means of a focusing lens at least two electron beams (28 to 35) on a display screen (5), which electron beams are deflected by deflection means and describe a frame on the display screen. The electron gun system (6) comprises at least two electron sources (20 to 26) the electrons of which in each electron beam are accelerated immediately after the electron source by means of an electric field having a field strength exceeding 600 V/mm, the central paths (36) of the electron beams extending substantially parallel to each other, all beams being converged by the focusing lens in or in the immediate proximity of the focus of the focusing lens, after which each separate beam is focused on the display screen by the focusing lens to form a spot also in the case of deflection by the deflection means. The astigmatism and the coma of the focusing lens, especially for objects not situated on the axis, decreases rapidly with decreasing object potential with the beam aperture angle being kept the same. The electrons leaving the source at a low potential are then accelerated in a strong electric field exceeding 600 V / mm. In this manner, nearly immediately after the electrons have left the electron source, a very slim electron beam is obtained which maintains its slimness up to the display screen. The effect of the field curvature of the focusing lens is also considerably reduced by said slim beams. If all electron beams through the focusing lens converge in or in the immediate proximity of the focus of the focusing lens, a minimum of aberrations as a result of the deflection is obtained. The electron sources are preferably P-N cathodes or diode electron guns.

Abstract: A computer aided design system comprises a processor which has access to different instruction memories. In a 2D mode of operation, the processor executes only the information stored in a 2D instruction memory, said instructions only referring to 2D geometry. If the processor receives a command related to 3D geometry, control is transferred to a transformation instruction memory which converts 2D geometry into 3D geometry and performs a topology check. Then (or upon entering of a 3D command) control is transferred to a 3D instruction memory which performs the necessary steps in 3D. The invention also relates to the method of system performance which allows easier and faster processing of geometric information.

Abstract: The process described herein comprises the application of chilled particles such as polytetrafluoroethylene generally marketed under the trade mark "TEFLON", graphite, molybdenum sulfite, boron nitride, etc., to a metal surface having crevices or pores therein. With the metal heated to expand the crevices or pores and the particles chilled to con­tract them, the particles will be locked into the pores when both the metal and the particles come to equilibrium temperature with the parti­cles thereby expanding and the pores contracting. The process described herein is directed to such an application of chilled particles to expanded pores in large metal objects such as for example, large rolls (1). The large object is rotated on its linear axis (2) while maintained at the desired raised temperature and the particles are given an electrostatic charge and chilled prior to their application to the metal surface. Apparatus for effecting this application of electrostatically charged chilled particles is also described.

Abstract: A one step RMS system in which an air core toroid coil (30) is used to measure the first differential with respect to time of a current signal waveform. The RMS value of the current signal waveform is determined directly from the first differential waveform generated by the air core toroid coil (30) by mathematically integrating the first differential waveform. The integration is performed by converting the signal into digital form and by sampling N times per piece of waveform or time period being analyzed. The value of N can be chosen so that the entire half cycle is sampled. Thus, the RMS value to be calculated will be based on the whole half cycle time period not merely a part of the half cycle time period. Alternatively, the RMS value of segments of a pulse with a long duration can be measured. As each sampling and conversion is completed, the digital number, representing the instantaneous value of the amplitude of the differential waveform, is used to determine the instantaneous value of the current at that time. This current value is squared and added to the sum of the prior squared values. Each squared value is summed until N samplings and conversions have been made. At this point, the final total is divided by N, and the square root is then taken to obtain the RMS value.

Abstract: A card reader contains an admission chamber, a fixed guide path, including card feeding rollers, and a read station for a magnetic track of a data bearing identification card. The read station and idler wheel are on opposite sides of a card guide path. The read station comprises first and second heads, respectively mounted to turn about first and second parallel axes that extend in the same direction as the guide path. Shafts defining the first and second axes are mounted at the extremities of first and second swing arms positioned on opposite sides of the heads. The swing arms are mounted to turn about a third axis that extends toward the guide path. A shaft defining the third axis is carried on a bifurcated bracket, mounted to rotate about a fourth axis that also extends in the guide path direction. A tension spring exerts a force on the bifurcated bracket to hold the heads constantly against a face of the car as it travels through a nip formed between the heads and a drive roller.
